Rexroth A4FO Axial Piston Fixed Pump is compact and effective pump, designed for hydrostatic drives in an open circuit. These pumps come with axial piston swashplate design, which make them perfect for a range of stationary and mobile applications. These pumps are available in multiple sizes from 22 to 500, featuring nominal pressure 400 bar and maximum pressure 450 bar. They are also designed in high pressure/ larger sizes from 71 to 500, with a nominal pressure of 350 bar and a maximum pressure of 400 bar.

A4FO pumps are developed with low noise level, long service life and economical design, making it ideal for applications requiring consistent performance even in harsh environments. They feature streamlined design, which enables integration into confined installation places without sacrificing performance. Their strong suction capabilities and low noise levels further make it a popular choice for those seeking a reliable and efficient hydraulic pump.

Their through drive for combining additional pumps options enable the addition of more pumps to the system, which makes them versatile and demanding for complex machines. These pumps are constructed with premium hydraulic fluids to function perfectly across a broad temperature and viscosity range. Rexroth A4FO pump offers a cost-effective solution for both stationary and mobile applications such as such as excavators, loaders and bulldozers.
